The energy added to a stream of fluid flowing through the blades in a blade row:
where
1 is upstream and 2 is downstream
ω is the rotor angular velocity
r is the distance from the axis of the stream tube upstream and downstream
v is the swirl (tangential) velocity component of the fluid velocity upstream and downstream
u is the impeller tip speed, which is defined as, u = (diameter in inches X RPM)/229.18
